Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 18274 was prepared by the European Committee for Standardization (CEN) in collaboration with
Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 3, Welding consumables,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
Throughout the text of this document, read “...this European Standard...” to mean “...this International
Standard...”.
It should be noted that, with regard to the corresponding EN standard, the designations given in Clause 9
have been adapted to the needs of international standardization.

Foreword
This document (EN ISO 18274:2004) has been prepared by Technical Committee CEN/TC 121 “Welding”, the
secretariat of which is held by DIN, in collaboration with Technical Committee ISO/TC 44 “Welding and allied
processes”.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by September 2004, and conflicting national standards shall be withdrawn at the
latest by September 2004.
Annexes A, B and C are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
--```,,,-`-`,,`,,`,`,,`---
For nickel welding consumables there is no unique relationship between the product form (solid wire, strip or rod)
and the welding process used (e.g. gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding,
submerged arc welding, strip overlay welding, laser welding or other welding processes). For this reason the solid
wire, strip or rod may be classified on the basis of any of the above product forms and can be used as appropriate,
for more than one of the above processes.

1
Scope
This standard specifies requirements for classification of solid wires, strips and rods for fusion welding of nickel and
nickel alloys. The classification of the solid wires, strips and rods is based on their chemical composition.
2
Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).
EN ISO 544, Welding consumables – Technical delivery conditions for welding filler metals – Type of product,
dimensions, tolerances and markings (ISO 544:2003).
ISO 31-0:1992, Quantities and units – Part 0: General principles.
ISO 14344, Welding and allied processes – Flux and gas shielded electrical welding processes – Procurement
guidelines for consumables.
3
Classification
The classification is divided into two parts:
a)
the first part indicates the product form being solid wires, strips or rods, see 4.1;
b)
the second part gives a numerical symbol indicating the chemical composition of the solid wire, strip or rod,
see Table 1.
4
Symbols and requirements
4.1
Symbols for the product form
The symbol for the solid wire and rod shall be S and for the solid strip it shall be B.
NOTE
One product form may be used for more than one welding process.

4.2
Symbol for the chemical composition
The numerical symbol in Table 1 indicates the chemical composition of a solid wire, strip or rod, determined under
conditions given in clause 6. The first digit is an indicator of the alloy group as follows:
Significant molybdenum addition without significant chromium addition (nickel-molybdenum alloys).
2
No significant alloy addition.
4
Significant copper addition (nickel-copper alloys).
5
Significant copper additions with aluminium and titanium for precipitation hardening.
6
Significant chromium addition, with iron less than 25% (nickel-chromium-iron and nickel-chromiummolybdenum alloys).
7
Same as 6, but with aluminium and titanium for precipitation hardening.
8
Significant chromium addition, with iron more than 25% (nickel-iron-chromium alloys).
--```,,,-`-`,,`,,`,`,,`---
1
The remaining digits indicate the particular alloy deposited. The basis of the system of designation is described in
annex B (informative).
NOTE
In addition the chemical symbol may be used.

(informative)
System for designation of welding filler metals
The system provides for one or two initial alpha designators, the first letter describing the type of filler metal and the
second, the alloy system. A four-digit numeric designator follows the initial letters and, for a number of alloy filler
metals, this designator is similar to those assigned by the Unified Numbering System (UNS). In this way, the filler
metals are frequently related to the base metals with which they are often used (see annex A). 1)

System for Designating Welding Filler Metals – Proposal for Submission to ISO” (IIW Document XII-1141-89), and
subsequently updated and published in Welding in the World, May-June 1996, pp 155-160, and in the Welding
Journal February, 1998, pp. 29-32. The aim is given as development of internationally accepted designations for
welding filler metals, since national designation systems are not readily changed and a generic system will allow
comparability among the various national specifications.
